8.4" Polished Shark Bay Stromatolite Fossil - 1.65 MYO

This is a 8.4" wide, polished slice of 1.65 million year old Stromatolite fossils from near Shark Bay in Western Australia. Shark Bay also happens to be one of the most famous locations where modern day stromatolites are found. Oncolytic stromatolites are spherical rather than domal in nature and are formed around a nucleus such as a shell fragment or grain of sand.

About Stromatolites

Stromatolites are fascinating, ancient rock formations created by the activity of cyanobacteria and other microorganisms. These layered, mound-like structures represent some of the earliest evidence of life on Earth, dating back over 3.5 billion years. Often found in shallow, warm waters, stromatolites form as layers of sediment and minerals are trapped and bound by microbial mats, gradually building up over time into unique, textured shapes.

Visually, stromatolites can range from smooth, rounded forms to intricate, banded structures, with colors that span earthy reds, browns, greens, and grays. Each layer captures a record of environmental conditions at the time of its formation, making stromatolites an invaluable source of information for scientists studying Earth’s early history and the origins of life.

Today, fossilized stromatolites are highly prized by collectors, both for their scientific significance and their natural beauty. Some living stromatolites can still be found in a few rare locations around the world, such as Shark Bay in Australia and certain alkaline lakes.
